In this case, I fear the Program Dependency Graph that
the use-defs I illustrated are a component of will not be so
useful to you.
This PDG is computed from the results of a static
analysis that can already tell if a variable is definitely
uninitialized.

There are plenty of precision/cost ratios to explore, but
if you decide to rely on Frama-C's analysis, then
your analysis' cost cannot be lower by definition and
your analysis' precision can probably not be better.

I hope it will nevertheless be useful to you as a comparison
point.
